Slavery was not racially motivated. That stigma needs to end. Africa was just a good place to get cheap people. Slavery was also slapped on the civil war as some humanitarian front to sell the war. The confederate states seceded, making them sovereign entities, therefore the US would have zero business even telling them that they had to abide by even the constitution.
